Threshold-based Monitoring of Compound Muscle Action Potentials for Percutaneous Pedicle Screw Placement in the Lumbosacral Spine: Can We Rely on Stimulation of the Uninsulated Screw to Provide a Valid Safety Warning?
Conclusion.
Screw stimulation with threshold hunting algorithm has a distinct advantage over the time-consuming insulated pilot hole stimulation, allowing an uninterrupted flow of the surgery. The present findings have documented practical usefulness and reliability of CMAP monitoring using direct stimulation of the PPS assembled to uninsulated extender sleeve. (Source: Spine)

The Clinical Impact of Failing to Achieve Ideal Proportional Realignment in Adult Spinal Deformity Patients
Conclusion.
In ASD patients who meet age-adjusted realignment goals, GAP proportionality does not significantly alter complication rates. However, GAP proportionality remains an important consideration in patients with sub-optimal age- adjusted alignment. In these cases, severe global disproportion is associated with higher rates of reoperation, implant failure, rod fracture, and junctional failure. (Source: Spine)

Rates of Loosening, Failure, and Revision of Iliac Fixation in Adult Deformity Surgery
Conclusion.
Lumbopelvic fixation failure rates were high following ASD correction, and associated with lesser clinical improvements. S2AI screws were more likely to demonstrate loosening, but less commonly associated with rod fractures at the lumbopelvic region. (Source: Spine)

Predicting Mortality in Elderly Spine Trauma Patients
Conclusion.
The incidence of spine trauma in elderly patients continues to increase. Previous publications described preexisting conditions that imply increased mortality, but ours is the first to develop a predictive calculator. Prospective research is planned to externally validate this model to better determine its predictive value and utility in the clinical setting. (Source: Spine)

Delineation of Inner Annulus Fibrosus and Nucleus Pulposus on Routine T2-weighted MR Images
Study Design.
Retrospective study of 150 IVDs.
Objective.
Assessment of costume algorithm ability to delineate the IAF and NP on routine T2 images.
Summary of Background Data.
Central hyperintense region on T2-weighted MR images of normal lumbar IVDs represents a combination of IAF and NP. Ability to identify NP as distinct from IAF can help improve our understanding of IVD morphology in-vivo.
Methods.
Sagittal T2-weighted TSE MR images of 150 lumbar IVDs from 25 patients were analyzed. MR images were processed using a custom algorithm that markedly increased the signal intensity of structures with...

Morphologic Change of CorticoCancellous Allograft Used for Anterior Cervical Discectomy and Fusion
Study Design.
Retrospective cohort study
Objective.
The aim of this study was to evaluate the incidence and clinical implications of graft morphologic changes in corticocancellous allografts used for anterior cervical discectomy and fusion (ACDF), such as graft resorption or fracture.
Summary of Background Data.
Although cortico-cancellous allograft is one of the most commonly used interbody spacer for ACDF, clinical implications of allograft resorption or fracture is unclear.
Methods.
One-hundred and thirty-eight consecutive patients who underwent ACDF for degenerative cervical myelopathy or radic...

Increased Cervical Spinal Instability is Associated With the Development of Proximal-type Cervical Spondylotic Amyotrophy
Conclusion.
This study suggested that a wide C3/4 flexion angle and high C3/4 or C4/5 spinal instability were closely associated with the etiology of proximal-type CSA. (Source: Spine)

A 3D-printed Personalized, Combined, Modular Pedicle Subtraction Osteotomy Guide Plate System: An Experimental Study
Conclusions.
The new 3D-printed PSO guide plate system can be used for preoperative osteotomy planning and demonstrates good accuracy. The results can be used to develop 3D-printed plans for PSO in clinical practice. (Source: Spine)

Evolution of Proximal Junctional Kyphosis and Proximal Junctional Failure Rates Over 10 Years of Enrollment in a Prospective Multicenter Adult Spinal Deformity Database
Study Design.
Retrospective cohort study.
Objective.
The aim of this study was to investigate the evolution of proximal junctional kyphosis (PJK) rate over 10-year enrollment period within a prospective database.
Summary of Background Data.
PJK is a common complication following adult spinal deformity (ASD) surgery and has been intensively studied over the last decade.
Methods.
Patients with instrumentation extended to the pelvis and minimum 2-year follow-up were included. To investigate evolution of PJK/proximal junctional failure (PJF) rate, a moving average of 321 patients was calculated across ...

Effects of Radiation on the Bone Strength of Spinal Vertebrae in Rats
Study Design.
A controlled laboratory study.
Objective.
The aim of this study was to examine bone damage caused by irradiation to spinal vertebrae in rats.
Summary of Background Data.
Radiotherapy is widely used in the treatment of malignant spine tumors. However, a few studies have reported vertebral fractures following radiotherapy as an adverse reaction. There are no reports on irradiation- induced changes in bone fragility, mechanical and structural changes focusing on the spine, and the mechanism of irradiation-induced bone osteoporosis.
Methods.
Eighty-four female Wistar rats were randomly al...
